Answer 1

Step-by-step explanation:

Given :-

A = {1, 2, 3}

B = {2, 3, 4}

To find :-

Find (AnB) X A ?

Solution :-

Given sets are :

A = {1, 2, 3}

B = {2, 3, 4}

AnB = {1, 2, 3} n { 2,3,4 }

AnB = {2,3}

Now

(AnB) X A

=> { 2,3 } X { 1 , 2, 3 }

=> { (2,1) , (2,2) , (2,3) , (3,1) , (3,2) , (3,3) }

Answer:-

(AnB) X A for the given problem is

{ (2,1) , (2,2) , (2,3) , (3,1) , (3,2) , (3,3) }

Used formulae :-

• The set of common elements in both sets A and B is called the intersection of A and B sets is denoted by AnB .
• A n B = {x: x ∈ A and x ∈ B}.

• The set of all possible ordered pairs where the elements of A are first and the elements of B are second is called The Cartesian product of two sets A and B, denoted A × B,
• A × B = {(a, b) : a ∈ A and b ∈ B}.
